RAILROAD-TIE.

Specification of Letters Patent.

Patented May 21, 1907 Application filed February 8,1907. Serial No.356,355.

Keokuk, in the county of Lee and State of Iowa, have invented certainnew and useful Improvements in Railroad-Ties, of which the following isa s ecification,-referen'ce being had therein to t e accompanyingdrawings.

This invention relates to improvementsin railroad ties, and the objectof the invention is the provision of a tiewhich will prevent sagging ofthe rails at the joints thereof.

' 'att A further object of the invention is the provision of tiesarranged to extend lon itudinall ofthe rails to prevent sa ging t ereoflie joints, which tiesare rigir 1y connected to prevent spreading of therails. A further object of the invention is the .provision of improvedmeans for reinforcing the wooden ties commonly in use, and pre: servingthe same from decay.

Other objects of the invention will be apparent from the detaileddescriptionhereinafter, when read in connection with the ac-,

companying drawings forming a part hereof, wherein a preferableembodiment of my invention is shown and wherein like numerals ofreference refer to similar parts in the several views.

In the drawings, Figure 1 is a plan view of.

a section of railroad track equipped with our improved ties. line 2-2 ofFig. 1. Fig. 3 is a cross section on line 33 of Fig. 1.

Referrin drawings, A indicate the rails, which are supported u on crossties placed at suitable intervalsan longitudinal ties interposed betweenthe cross ties.

The cross ties each comprise an elongated metallic trough. B,- which ispreferably formed of sheet steel, and in which is positioned the usualwooden tie B, to which the bases of the rails A-A are ada ted to bespiked in the usual manner. T e wooden ties B are secured within thetrough mem bers B by means of U-shaped clips 0, which are preferablystamped from sheet steel, and which are secured across the tops of thetrough members, the arms of said clip being arranged to overlie thesides of said trou h members and being riveted thereto. T e

Wooden ties B are held against longitudinal.

movement in the trough members B by Fig. 2 is a cross sectionlon nowmore particularly to the r means of spikes b, which are driven thereinand the heads of which engage opposite edges of the clips C.

In the form of-our invention disclosed in the drawings we have shown thetrough members B as each provided with two wooden ties B, which is avery economical structure, as it permits of the utilization. of the oldor worn ties which have hitherto had to be discarded. It will beobvious, however, that a single tie may be secured within the troughmembers if desired. The longitudinal ties each comprise an elongatedtrough member C which is preferably stamped'frorn sheet 0 The ends ofthe trough members C are thereof whicv are designed to overlie the topsof the ties B secured within the trough mempassing therethrough and enaging sai ties.

. Interposed between the ad the longitudinal trough members C aresleeves 0, through which pass tie rods 0 the opposite ends of which passthrough the side walls of the trough members 0 and the ties C seatedtherein. The tie rods 0 are each provided at one end with a suitablehead and at the other end with a nutor other fasten ing device, so thatthe sides of the trough gagement with the ends of the sleeves c and thelongitudinal ties and the rails carried thereby may be maintained at theproper distance apart, thereby preventing any spreading of the rails.

The" bottoms of the .trou h members B and C are each provided wit aplurality of any water which may accumulate in said trough. It will beseen from this construction that the metallic troughs not only serve tostrengthen and reinforce the Wooden ties, but also toprot'ect them frominjury and de-' ca r We do not desire to limit ourselves to the preciseform and construction shown in the drawings, as it is obvious that manyminor changes may be made therefrom without departing from the spirit ofthe invention, as defined in the appended claims.

Claims.

1-. In a railway track structure, a pair of longitudinal ties, aplurality of sleeves interposed between said ties, and tie rods conbersB, and are secured thereto by s ikes members 0 may be drawn tightly intoenapertures a therein to permit the escape of steel, and in which issecured a wooden tie closed and are provided with laterally projectingflan es 0 extending from the tops jacent faces of necting said ties andpassing through said sleeves.

2. In a railway track structure, separated ties each comprising ametallic trough, a Wooden tie seated therein, and tie rods conheatingsaid ties, the extremities of which pass through the sides of themetallic troughs and the ties seated therein.

3-. In a .railway track structure, a pair of cross ties, a.pai-r oflongitudinal ties interposed between said cross ties and having theirends secured thereto, a plurality of sleeves interposed between theadjacent sides of the longitudinal ties, and tie rods connecting thelongitudinal ties and passing through said sleeves.

4. In a railroad track structure, a pair of separated cross ties andlongitudinal ties in terposed therebetweemeach of said longitudinal tiescomprising a metallic trough'having ilanges extending from the endsthereof and overlying the cross ties and a Wooden tie secured withinsaid trough.

5. In a railroad track structure, a pair of cross ties each comprising ametallic trough and a wooden tie seated therein, and a pair of separatedlongitudinal ties interposed therebetween, each of said lon itudinalties c 11- prising a metallic trough aving fianges' extending from theends thereof, and 0V6 rly' ng the cross ties and a wooden tie seatednsaid metallic trough, and tie rodsconnecting said
